' Application filed July 10, 1922. SeriaiNo. 574,050.

To all whom it may concern:

Be it known that DANIEL G. SELL, cltizen of the United States, residing at Kansas City, in the county of Jacksonand State of Missouri, has invented certain new and useful Improvements in Drip Coffeepots, of which the following is .alspecificatiom reference being had thereiii to the accompanying drawings.

The invention relates to dri 'coffee pots and has for its object provi e a device of this character wherein ,steam from water within a coffee pot` passes upwardly intoventional form of coffee pot, said receptacle having detachably supported on its upper end a casing having an opening in the bottom thereof, and lugs adjacent the opening and an auxiliary casing formed in two sections and supported 0n the lugs and having its lower end extending through the openingin the main casing and provided with a fabric; member in which coi'ee may be placed. The downwardly extending portion of the auxiliary casing being spaced from the Wall of the openin in the bottom of the main 'casing and a col water pan supported on the upper end of the main casing and having its lower end extending into the upper end of the auxiliary casing and out of engagement therewith, and forming means for condensing steam.

A further object is to provide the bottom of the co'ld water pan with a roughened surface whereby condensation will take place over its entire surface, and water dropped.

over the entire bulk of coii'ee. Also to provide a steam exhaust pipe extending upwardly through the water receiving pan and forming means for insuring a circulation of steam. A

With the above and other objectsl in view `the invention resides in-the combination and yarrangement of parts as hereinafter set forth, shown in the drawings, described andclaimed, it being understood that changes -in the precise embodiment-of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing Figurev 1 is a vertical sectional vview through the device showing the same supported on a conventional form of coffee pot.

Figure 2 is a top plan view of the device.

Figure 3 is a perspective view of the auxiliary casing, part being broken away to bet ter show the structure.

Figure 4 is a sectional View through a combined Water still and cofi'ee pot, showing the device applied thereto.

Referring to the drawing, the numeral 1 designates a conventional form of coffee pot, in which water 2 is placed, the coffee pot being adapted to be disposed on a stove or the like for heating the water. Supported on the upper end of the coffee pot 1 is the main casing 3, theilower end of which is provided with a horizontally disposed flange 4, which rests on the upper end of the coffee pot 1j vand is held against lateral displacement byk means of the annular fiange 5, whichv extends downwardly into the pot 1 and forms an opening in the bottom of the main casing 3. Extending upwardly from the flange 4 are spaced lugs 7, which lugs engage the downwardly and inwardly inclined flange 8 of the auxiliary casing 9 and support'the same spaced from the flange 4in such a manner that steam may pass in the direction ofthe arrow a. Supported on the flange 8 of the auxiliary casing 9 by means of a flange 10 isa coffee receiving cup 11, which extends downwardly axially through the opening 6 and spaced from the wall thereof in such' a' manner that steam may pass from the chamber of the ot 1 in the direction of the arrow b. The ower end of the coffee receiving cup 11 is provided with a horizontally disposed flange 12, which supports the'cofiee strainer 13, preferably formed of fabric andsupported by a ring which rests on the flange 12. The outer periphery of the wall of the main' casing 3 thereby forming an annular steamv passage 15 through which steam passes upwardly from the chamber of the pot 1. The upper end of the auxiliary casing 9 is lower than the upperend of the main casing 3, the purpose of which will presently appear.

Supported on the upper'end of the main Ioo auxiliary casing 9 isl spaced from the inner' los casing 3 by means of its fiange 16 resting on the upper end of the casing 3 is a cold Water paul?, which pan preferably tapers downwardly and inwardly and is provided with a flat bottom 18 disposed within the upper end of the auxiliary casing 9, but spaced from the wall thereof', thereby forming an annular passage in communication with the annular steam passage l5, whereby steam may pass from the passage 15 in the direction of the arrows c. The steam generated in the pot 1 passes downwardly through the bag 13 and coffee therein, engaging the roughened bottom 18 of the cold water pan 17, where it condenses and the drops accumulate on the roughened surface of the bottom in such a manner that they drop from all parts thereof into the cup 11 thereby insuring the passage of distilled water through the entire body or bulk o f coffee insuring the uniform extraction from all of the coffee. To insure circulation by allowing the exhaust of a limited amount of steam, a pipe 19 is provided. which pipe extends upwardly through the bottom of the cold water pan 1T and discharges to the atmosphere.

From the above itwill be seen that a 'coffee making receptacle is provided which may be easily and quickly attached to a conventional form ot' coffee pot, and that the device may be easily and quickly assembled or disassembled for use or cleaning purposes. It will also be seen that means is provided for insuring the dropping of condensed steam onto the entire bulk of coffee thereby allowing and insuring the extraction oi" all of the strength from the coffee.

Referring to Figure 4 wherein the device.'

is shown as supported on a cmnbiudd coffee pot and still, the device works in substantially the same manner as that shown in Figure 1, however the receptacle l*l is divided into a coffee chamber 1b and a water chamber 1c, the water in the water receptacle 1c vaporizing and condensing, thereby forming a still, and the water may 'be used by opening the faucetl 1"; Water may be added to the receptacle 1c by pouring the same into the passage l and additional Water may be added to coffee within the chamber 1" by pouring the same through the passage 1f. lVhen it is desired to draw coffee from the chamber l, the faucetle' is opened.

The invention having been set forth what is claimed as new and useful iszl. A coffee making utensil comprising a water receptacle adapted to be placed over a fire and having its upper end opened. a. main receptacle supported -on the upper end of the water re yeiving receptacle and hav-V ing an opening in its bottom. an auxiliary reccf'itacle disposed within the main receptacle and smaller than the mainv recel'itacle. supporting lugs for supporting the bottom of the auxiliary receptacle spaced fron. the

bottom of the main receptacle, a coffee receiving cup disposed within the auxiliary rethe main receptacle and extending through' the Aopening in the bottom thereof and spaced from the Walls of the main recepotacle, a coffee receiving bag in the bottom of the auxiliary receptacle, a cold Water receiving pan supported on the upper end of f the main receptacle and extending idownwardly into the upper end of the auxiliary receptacle and spaced lfrom the walls thereof, the bottom of said cold water pan being roughened.

A coffee making utensil comprisingr a water receiving receptacle. a main casing supported on the water receiving receptacle and having an opening in the bottom `thereof, upwardly extending lugs carried b v the main receptacle. an auxiliary casing sup ported on said lugs, a removable coffee re ceiving cup disposed in the lower end of the auxiliary receptacle. Ia cold water receiving pan supported on the upper endV ot' main casing and extending downwardly 'into the upper end of the auxiliary casing. the `bottom of the water receiving pan being roughened. and a pipe extending upwardlv through the water receiving pan.

4. The combination with a coffee pot. vof a main casing supported thereon and having an opening in the bottom thereof. upwardly extending lugs carried by the bottom ofi' the main casing, an auxiliary casing withinvthe main casing and spaced from the walls thereof` the lower end of said auxiliary casing being provided with an inwardly and downwardly extending flange resting on the lugs. a coffee receiving rcceptacle supported on the flange ot" the auxiliary casing and extending downwardly into the coffee pot, a water receiving pan `supported on the upper end -of the main casing and extending downwardly into the upper end of the auxiliary casingQthe hottom of the water receiving pan being roughcned. and a pipe extending upwardlythrough the bottom of the water receiving pan.
